Teeth names are created by a combination of 4 different characteristics: 1  The jaw where they are located: upper and lower (alternatively the terms maxillary and mandibular can be used) 2  The side of the face: left and right.  The type of tooth: incisor, canine, premolar, and molar.
Vampire bats are members of the New World Leaf-nosed bats, the Phyllostomidae. All three species of living vampire bats occur in South and Central America. Fossils of three other species reveal that several thousand years ago vampire bats were more widespread.
One of the main differences among the species of bats has to do with their diet. About 70% of them consume insects and bugs. The rest of them rely on various types of fruit to feed upon. Only a select few species known as the Vampire Bats actually consume blood. The survival instinct of the bat is one that is very strong. Many researchers are fascinated with the way in which they have evolved. Many species of bats rely upon echolocation in order to help them be able to locate their prey.
